Default top off R22

Stash of R22 about gone.

Figure to top off from now on when needed with R290 (or BBQ)

Will just fill for 10 deg superheat, do not forsee any problems or other complexity.

Overlooking anything? (BBQ would be run thru filter dryer first)

Note: already figured that air fuel mix would remain below ignition even with 100% leak.
